US-based Newmont Mining is facing a new controversy concerning the pending Conga mega-mine, to be developed by its majority-owned subsidiary in Peru's Cajamarca region. Milton Sánchez, leader of the Interinstitutional Platform of Celendín, charged that the Yanacocha mining company is preparing to start removal of water from Laguna El Perol to an artificial reservoir in order to facilitate turning the site of the lake into an open-pit mine. He further charged that Peru's National Water Authority has changed the director of its local administrative region, VI Marañón, in order to allow this work to move ahead. Sánchez said the new regional director, Carlos Enrique Gastelo Villanueva, was brought in after his predecessor refused to sign off on "relocation" of the lake. Sánchez said his followers are prepared to begin a sit-in at the regional offices of the Water Authority if approval is given for the water transfer. (Celendin Libre, Sept. 11)

On Sept. 6, a confrontation at a protest roadblock in Peru's province of La Convención, Cuzco region, saw a vehicle fall into a canyon of the Rio Vilcanota, leaving two dead, including Rosalío Sánchez, mayor of the pueblo of Kepashiato. In a similar incident four days earlier, a 16-year-old youth was shot dead by National Police troops in a confrontation at a roadblock. The province has been paralyzed by a general strike since Aug. 27, to demand action on several outstanding petitions to the national government, some dating back five years. Demands include construction of a local gas processing plant; the remote jungle valley of La Convención is impacted by the Camisea gas pipeline, yet the price for gas is much higher locally than in Lima and other urban areas of the country. The Central Struggle Committee of La Convención is also demanding an investigation of local mayors and officials who they say have embezzled monies from the pipeline "canon," compensation funds to local communities for development of the project in their area. Some 1,500 National Police troops have been mobilized to the valley. (La República, Lima, Sept. 8; El Pais, Spain, Sept. 6)

The State Civil Protection Unit (UEPC) of the northern Mexican state of Sonora issued a new alert on Sept. 21 warning some 25,000 residents about likely contamination in the Bacanuchi and Sonora rivers from the giant Buenavista del Cobre copper mine in Cananea. According to Arizpe municipality president Vidal Vázquez Chacón, who reported the contamination a day earlier, the source was a leak in the temporary dam set up to stop the overflow of toxic substances after 40,000 cubic meters of copper sulfate acid solution spilled from the mine into the two rivers on Aug. 6. Spokespeople for Grupo México, the company that owns and operates the mine, said the latest overflow was caused by heavy rains associated with Hurricane Odile in mid-September. The 115-year-old mine makes $1 billion annually by producing some 200,000 tons of copper each year. (La Jornada, Mexico, Sept. 21; Associated Press, Sept. 21, via Salon)

At least 800 members of Section 65 of the National Union of Mine and Metal Workers and the Like of the Mexican Republic (SNTMMSRM, "Los Mineros") began blocking the three main entrances to the giant Buenavista del Cobre copper mine in Cananea, near the US border in the northwestern state of Sonora, on Aug. 20 to protest environmental damage caused two weeks earlier when about 40,000 cubic meters of copper sulfate acid solution spilled from the mine into the Bacanuchi and Sonora rivers. Most of the unionists lost their jobs four years ago when the mine's owner, Grupo México S.A.B. de C.V., broke a 2007-2010 strike over health and safety issues. "During the strike we made several complaints about the improper and inadequate measures Grupo México implemented for preventing overflows from the dams" for chemicals and heavy metals, Section 65 director Sergio Tolano Lizárraga told the national daily La Jornada. He said the blockade would continue until the company recognized the workers' old contract. (LJ, Aug. 22)

After the abduction of more than 500 Yazidi women and girls by ISIS fighters at Sinjar, the jihadist group has established a special office in the Quds neighborhood of Mosul city where the women are being sold, according to Evar Ibrahim, head of the Women's Committee in the Kurdistan Regional Government's parliament. Ibrahim said the girls are being sold for 30,000 dinars, or about $26. "Despite selling them, the Yazidi girls have been raped by the IS insurgents," Ibrahim added. (BasNews) An official spokesman of Patriotic Union of Kurdistan (PUK) in Khanaqen district, Hemin Mansour, charged that ISIS militants are evicting any remaining Kurdish families from Jalawla (Diyala governorate), and have demolished some houses belonging to Kurdish residents of the town. The evictions are being justified on the grounds that the Kurdish families were collaborating with the Peshmerga. The ISIS flag is also being raised over seized Kurdish homes to make them a target for air-strikes. (BasNews)

The taking of the Mosul Dam on the Tigris River from ISIS by Kurdish Peshmerga forces backed by US air power highlights the strategic nature of water in the multi-sided Iraq conflict. Even before ISIS seized the giant dam in early August, the militants were taking advantage of the country's drought, cutting off the flow of water from the dam to Baghdad through territory under their control. "ISIS is starting to use dams as weapon of war," wrote meteorologist Eric Holthaus, Slate's Future Tense blog. "So they've made [it] high on their list to take over those dams and control the water downstream." July saw battles between ISIS militants and government troops over the Haditha Dam and its hydroelectric works on the Euphrates. The fall of the complex to ISIS would have given the rebels control over Baghdad's electricity source. But the most grave danger has not passed: ongoing fighting and air-strikes in the area of the Mosul Dam could lead to the dam being breached, which would flood Mosul and other downstream cities, possibly even affecting Baghdad.

A Yazidi militia group has entered the fight against ISIS, clashing with militants near Sinjar. Khudida Kicho, a member of the Yazidi militia, said in a press conference in Erbil: "In the Kahbel area near Sinjar our fighters were able to attack IS militants and kill 24 of them. In the clashes three of our fighters were killed as well, but we will continue to fight terrorists until the end." (BasNews) Kurdish Peshmerga leaders meanwhile said their forces have seized full control of the Mosul Dam, in coordination with US air-strikes on ISIS positions in the area. (IraqiNews.com) But in Baghdad, the general command of Iraq's armed forces warned against foreign planes breaching the nation's airspace and arming "a certain Iraqi faction"—a clear reference to Western arming of the Peshmerga. "We welcome international support for Iraq in its war against terrorism," read the statement. "But Iraq's territorial sovereignty must be respected." (Rudaw, IraqiNews.com)

A survivor who managed to escape by feigning death described a general massacre at the ISIS-occupied Yazidi village of Kojo 20 kilometers south of Sinjar. The village was surrounded by ISIS fighters 12 days ago, with residents ordered to convert on pain of death. On Aug. 15, the fighters moved in, and rounded up the villagers, separating the men from the women and children. The men were lined up and machine-gunned. Up to 80 are believed to have been killed. (BasNews, AP, Reuters) ISIS forces have reportedly brought Sunni Arabs into the cleansed Yazidi town of Sinjar in response to US air-strikes on nearby Arab villages. Yazidi homes are being given to the Arab families. (BasNews) The Kurdistan Regional Government's Peshmerga forces have joined with PKK-aligned Kurdish militias to form the Sinjar Defense Units, to take back the town. (Rojava Report) The KRG's Peshmerga Ministry issued a statement naming several villages where "IS militants" suffered "heavy losses" under US bombardment. Peshmerga forces backed by US air-strikes have also opened an operation aimed at recovering the ISIS-held Mosul Dam.
